Delegates data and stack allocation to aslink.  Creates areas for register
banks.

+	Changes to aslink (All the changes are marked with 'JCF'):
+
+	* \sdcc\as\mcs51\aslink.h: External definition of sflag and
+	summary().
+
+	* \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
+	area BSEG.  Also moves, if possible, the DATA area down into the internal
+	ram so more space is available.
+
+	* \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
+	sflag.
+
+	* \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
+	not bytes.  Function summary() which creates a memory usage summary
+	file with extension .mem.  Reports of overlaping stack and small stack
+	size.  If the space for the stack is less than 16 bytes aslink trows a
+	warning.
+	
+	* \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
+	the 8051.  Option 'y' for memory summary output file.
+
+	Changes to sdcc (All the changes are marked with 'JCF'):
+
+	* \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
+
+	* \sdcc\src\SDCCglue.c:  If a register bank is used, creates an
+	overlaying area	for it (uses RegBankUsed[4]).
+
+	* \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
+	bank zero as used by default.  By default aslink locates the stack
+	(equivalent to --stack-after-data).  Pass option 'y' to aslink for
+	the creation of the .mem file.  Delegates the allocation of data area
+	to aslink (it is not longer 0x30 by default).  If --stack-loc passes
+	the begining of the stack area to aslink.
+
+	* \sdcc\src\SDCCmem.c:  If a register bank is used, marks it so
+	glue() in SDCCglue.c creates an area for it.
